在vb6中获取字符串数组的最后一个元素？

Question

如何在visual basic 6中检索字符串数组的最后一个元素？

我正在处理具有多个点的文件名,这些点被分成一个数组,我只想操纵扩展名.以下代码有效,但有一个我想删除的硬编码元素.

Private Sub Form_Load()
    Dim aPath() As String
    Dim FileName As String
    Dim realExt As String

    FileName = "A long dotty.file.name.txt"
    aPath = Split(FileName, ".")

    realExt = aPath(3) ' <-- how to not hardcode?'

    MsgBox ("The real extension is: " & realExt)
    Unload Me
End Sub

我认为使用Ubound应该可以解决问题:

Private Sub Form_Load()
    Dim aPath() As String
    Dim FileName As String
    Dim realExt As String

    FileName = "A long dotty.file.name.txt"
    aPath = Split(FileName, ".")

    realExt = aPath(UBound(aPath))

    MsgBox ("The real extension is: " & realExt)
    Unload Me
End Sub
